SRCU is as follows:\n\no\tEach use of SRCU creates its own srcu_struct, and each\n\tsrcu_struct has its own set of grace periods. This is\n\tcritical, as it prevents one subsystem with a blocking\n\treader from holding up SRCU grace periods for other\n\tsubsystems.\n\no\tThe SRCU primitives (srcu_read_lock(), srcu_read_unlock(),\n\tand synchronize_srcu()) all take a pointer to a srcu_struct.\n\no\tThe SRCU primitives must be called from process context.\n\no\tsrcu_read_lock() returns an int that must be passed to\n\tthe matching srcu_read_unlock(). Realtime RCU avoids the\n\tneed for this by storing the state in the task struct,\n\tbut SRCU needs to allow a given code path to pass through\n\tmultiple SRCU domains -- storing state in the task struct\n\twould therefore require either arbitrary space in the\n\ttask struct or arbitrary limits on SRCU nesting. So I\n\tkicked the state-storage problem up to the caller.\n\n\tOf course, it is not permitted to call synchronize_srcu()\n\twhile in an SRCU read-side critical section.\n\no\tThere is no call_srcu(). It would not be hard to implement\n\tone, but it seems like too easy a way to OOM the system.\n\t(Hey, we have enough trouble with call_rcu(), which does\n\t-not- permit readers to sleep!!!) So, if you want it,\n\tplease tell me why...\n\n[josht@us.ibm.com: sparse notation]\nSigned-off-by: Paul E.
